Measuring torque with Star

Hello
Does anybody know if it's possible to measure engine torque with the Star Diag system? The dealer I usually nag says it's not possible - maybe he's just telling me "go away and leave me in peace"!
Peugeot and Mazda systems can do this and the relative compression can be measured with Star so I would expect it to be possible to measure torque too.
 
You would normally need a dyno meter or Roto tester to measure output, if done with diagnostic equipment it can only be a hypothetical answer
 
Only way would be possibly theoretically, not familiar with star, but the latest system i use at work can measure load in % but this is theoretical and actual can only be measured with a dynanometer.
 
Nope, not possible with the star.
 
What does :confused:

No torque reading. Although I agree where you can "measure" this on other marques it more miss than hit from what I read.

So can you real time log with Star?

rpm, throttle openings, maf, temperatures, timing angle, retard etc?
 
Thanks to you all.
I know that Mazda M-MDS diagnostics system can do this but don't really know how. I will try to find out more.
I asked to measure relative compression on my car and the results where:

Cyl 1 276 (51%)
Cyl 2 277 (51%)
Cyl 4 275 (50%)
Cyl 5 276 (51%)
Cyl 3 276 (51%)

Does anybody know how to interpret these results? Dealer just told me the engine is fine but couldn't tell me what the numbers meant.
Thanks

The diagnostics can measure the "pulling power" of an engine without any method of metering this ?

Surely it would need some kind of resistance to measure the rotational forces on the wheels... unless you could do something with the flywheel etc..
So in theory then using this diagnostics software you could give the BHP by multiplying the lbft torque by it's RPM / 5252.

(Waits to be corrected).
